STEfAM-BILER ASH-PAN.

Specification of Letters Patent.

Patent-ed Aug. 3, 1920.

Application filed February 19, 191.8. Serial No. 218,122.

To all whom t muy concern Be it known that I, JASPER N. RaLsToN, a citizen of the United States, residing at Fitzgerald, in the county of Ben IIill and State of Georgia, have invented certain new and useful Improvements in Steam-Boiler Ash-Pans; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a steam boiler ash pan. Y The object of the present invention is to provide a simple, practical and ecient steam boiler ash pan designed particularly for use on railroad locomotives and to eliminate the expense, delays and loss resulting from the use of locomotive ash pans of the ordinary construction.

T he ash pans ordinarily in use on locomotives do not hold their original shape when hot coal, ashes and clinlers accumulate within them. The hot substance warps the metal and opens the joints, allowing live coals to drop through and set lire to bridges, roadbeds, grass and the like, causing often considerable loss which results in expensive law suits and damages.

It is also an object of the present. invention to provide an ash pan equipped with means for maintaining it in a relatively cool condition and for delivering waterupon hot coals, clinlrers and ashes, and of enabling the same to be discharged in a safe condition.

Furthermore, the invention has for its object to reduce the expense of the Vash pan in the original construction, lessen the cost of' the upkeep and provine a pan which will be practically indestructible from warping and which will last for a comparatively long4 time.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described', illustrated in the accompanying drawing and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims, may be resortedto without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing: f

Figure 1 is a longitudinal sectional view which communicates with water spaces 4 and 5 of bottom sections 6 and 7. The bottom sections 6 and 7 are composed oi inner and outersheets spaced apart to form the intervening water spaces 4t and 5 and they are oppositely inclined as shown and are located between outlets 8 which are controlled by slides 9 mounted upon and guided by angle bars 10.

The inner sheet of the side and end walls terminates short of the upper edge of the outer sheet and the upper edge of the said inner sheet is spaced from the outer sheet to form an outlet 11 to permit the water, after filling the water spaces 3, 4 and 5, to overflow the inner sheets and flow down the face or" the walls of the ash pan for cooling the same and also for cooling the hot einders, ashes and coals, whereby the same will be effectively extinguished before they are discharged at the outlets 8 by the operation of the slides 9.

rEhe open spaces at the top of the side and end walls of the ash pan are covered by aprons or shields 12 composed of an upper attaching` flange 13, an'inwardly projecting horizontal connecting portion or web la and an inclined downwardly extending flange 15. The horizontal web or flange 141 and the inclined flange 15 are arranged in spaced relation with the upper edge of the inner sheet 1 so as not to interfere with the overflow of the water from the side and end water spaces 3. The aprons or shields are adapted to prevent ashes and other accumulation from closing the overflow outlet and interfering with the action or the water.

The ash pan is equipped with a hopper 16 mounted on the ash pan exteriorly of one endand consisting of an inclined bottom or side wall 17 and a horizontal top wall 18 which is provided with a filling opening l19. The end wall is provided in its outer sheet with an opening 2O constituting an outlet for the water to permit the same to How from the hopperinto the water space Y 3. The hopper may be connected with any suitable means for supplying the necessary amount of water. The overflow from the injector may be employedV and will over flow the ash pan each time the injector is operated. Alsofthewater from the exhaust pipe of the air pump and waste water from other appliances operated by steam may be used and a connection can be made directly -with the water tank it necessary and can .-be controlled by suitable means for enaand bling the water space to be kept full will overflowingY at all times. The water keep the inside ash pan sheets cool and thereby prevent the pan from warping and Will maintain it 'in' proper alinement. The water is fed into the hopper onk the outside sheet of the pan and when the water space i Y betweenV the inner and outer sheets is ful-l,

the Water overflows around the pan from under the wings of the apron or shield and rims down the inside "sheet, extinguishing all live fire'which may collect against the inside sheet. Y The water also Vruns down around the slide openings or outlets, thereby keepingthe live fire out and preventing` the slides or angle irons from warping. y this construction and operation'there is no liabil-z ity of fire leaving ythe ash pan and damaging the road bed or other property. 'The arrangement with ordinary care 'will be practically indestructible trom warping and will last for a long time in proper working order. The sidesoiE the ash pan are provided with inclined extensions 2l forming a flaring'top niouth and having uppersupporting portions 22.

vWhat is claimed is l. An ash pan of the class described including side and end. walls and bottom sectionsVVK having interiorly arranged Water spaces,'the side and end walls being coniposed of inner and outer sheets, theV inner sheet being spaced from the outer sheet atl the top to provide overflow outlets, and a laterally progecting hopper mounted eX- teriorly oi" the ash pan at oneend thereof and having an inlet opening, the outer s heet of the end wall of the pan being provided Witnesses Vpermit water tofflow over the inner sheet and down the same interiorly of the ash pan.

3. An ash pan of the class describedincludingV side and end walls and bottom sections having` -interiorly arranged water spaces, the side and. end walls being composed Vof innerV and outerl sheets, the inner sheet Vbeing spaced from the outer sheet at the top to provide overflow outlets, and an apron or shieldV mounted Von the upper portion of the outer'sheet interiorly oi' the pan and composed of an upper attaching flange, a horizontal approximately connecting flange or portion` and an inner depending flange, the outer horizontal flangeor portion and the inner flange being arranged in spacedrelation with the upper edge of the inner sheet.. Y

Ll. An ash pan ofthe class described in;

cluding sideand end walls and oppositely inclined bottom sections, said bottom sectionsand side and end walls being provided with water spaces having outlets to permit the water to flow interiorlyl of thefpan, said pan' being provided at the `bottom sections'V with outletsand controlling slides arranged to be cooled'by water flowing romjthe said Water spaces.

5. In anash pan of the class described having interiorly arranged water spaces pro- 'videdV with open upper ends, a shield arranged to extend over the open ends, of Vthe water spaces, wherebyY cinders or thc like will be prevented from entering said spaces.

In Vtestimony whereof l affix my signature in presence of two witnesses.
